Why Does it Stay in Orbit?

On Monday, the space shuttle Endeavor launched for the last time. The six astronauts on board docked this morning at the International Space Station to join the 6 astronauts and cosmonauts who live at the ISS.

Combine current events, Earth science, and parabolic motion in your math class. Students will use their understanding of exponents and practice converting speed and distance from metrics to US customary units to complete this exercise ... and, they will learn about space science in the process.

Radiation amounts

This investigation will help you and your students to better understand the magnitude of normal, background radiation and the more serious radiation exposure that comes from nuclear accidents.  Students will gain a realistic perspective on the seriousness of any event.

Our investigation on radiation measurements is pretty dense with information but allows students to become familiar with normal and abnormal radiation dosage and calculate yearly and lifetime dosages for people living in various regions and elevations in the US, Japan, and on the Space Station.

Unions and Collective bargaining

Protestors at the Wisconsin State House

There is a confrontation going on in Wisconsin. Governor Scott Walker is trying to enact legislation that would limit bargaining rights for most public employees in that state ... firefighters, teachers, police, child-care workers, and more. In response to this, state employees have been picketing in Madison for 2 weeks.
Labor unions in this country have been responsible for safety standards, the minimum wage, fair employment practices, and more. In Brian's latest data activity, students calculate for themselves who is better paid and by what percent. They are asked to consider which salaries are below the poverty level and to hypothesize how those salaries affect the daily lives of workers and their families.
